Practical Solutions for DC Traction Power Substation Grounding

This paper describes how a key component for the overall safety of personnel, reliability and electrical performance of DC traction power substations is the grounding system. Effective grounding enhances the fast draining and clearing of fault currents and improves the safety and dependability of an electrical system. High fault current levels can introduce the catastrophic risk of melting the grounding conductors if they are wrongly sized and not large enough to carry or handle the anticipated fault currents. There is great possibility of damaging electrical and electronic equipment connected in the substation during a fault condition. Also and more importantly, there is the safety risk to personnel who may be present. Grounding design and installation must meet the requirements of applicable codes and regulations. The IEEE Std. 80 – Guide for Safety in AC Substation Grounding and the IEEE Std. 142 – Recommended Practice for Grounding of Industrial and Commercial Power Systems are invaluable resources for the grounding design. Installation must be properly carried out in accordance with the design and then tested to ensure the design values are met. However, it is often found after installation that test results do not meet the design values.
